Scratch and sniff accessory for switch 2?

I would really like to see a scratch and sniff accessory for the Switch 2. Think about it. If you’re ever playing Mario Kart 8 and you’re on the candy course then you’d wanna sniff the air.

Or if Conkers Bad Fur Day ever got added to switch online, then you’d wanna sniff the great mighty poo’s den.

Nintendo could make a lot of money from this.
